Error: Request failed with status 400 (URL: https://relay.flashbots.net): {"error":"unable to decode txs"}

I keep getting that error when I try to simulate my transaction. This is the code:

[Fahadulhassan1]

 flashbotsprovider = await FlashbotsBundleProvider.create(
      provider,
      authSigner,
     "https://wallet relay url"
     "sepolia"
    );
  pass your relay url and network as well. even it's optional but optional is only for mainnet

I implemented your suggestion and it kinda worked. Now I am getting a new error "Simulation Error: the method eth_callBundle does not exist/is not available" Any idea what might be the problem?
